You are dead on about the saltwater intrusion (light term for intrusion, more like a bath) . The part number did show up as a relay so I am hoping I can take it to one of the auto stores and order a matching one. There was a red wire (12 ga) that is hot all of the time that was hooked into this at one time then three other wires. I am not sure if this somehow gets me power to the motor fan but that will play out once I get the new relay. Thanks
